They can be put in the category of primary consumers

Options

A. Eagles and tigers
B. Fishes and whales
C. Snakes and frogs
D. Insects and cattles.

Answer

**Step-by-Step Solution:**

1. **Understand the Concept of Trophic Levels**:
- In an ecosystem, organisms are categorized based on their role in the food chain. The main categories are producers, primary consumers, secondary consumers, and tertiary consumers.

2. **Identify Producers**:
- Producers are typically green plants or autotrophs that can produce their own food through photosynthesis. They form the base of the food chain.

3. **Define Primary Consumers**:
- Primary consumers are organisms that eat producers. They are usually herbivores, meaning they primarily consume plants.

4. **Examples of Primary Consumers**:
- Common examples of primary consumers include animals like insects (e.g., grasshoppers), cattle, deer, and rabbits. These organisms feed directly on plants.

5. **Distinguish Between Consumer Types**:
- Secondary consumers eat primary consumers (herbivores) and are usually carnivores or omnivores. Tertiary consumers are at the top of the food chain and eat secondary consumers.

6. **Evaluate Given Options**:
- If provided with multiple-choice options, identify which organisms are herbivores. For instance, if options include eagles (carnivores), tigers (carnivores), fishes (can be carnivores), and insects or cattle (herbivores), the correct answers would be insects and cattle as they are primary consumers.

7. **Select the Correct Answer**:
- Based on the evaluation, identify and select the organisms that fit the definition of primary consumers.

**Final Answer**: The organisms that can be put in the category of primary consumers are insects and cattle.
